Older algorithms like MD5 and SHA1 have vulnerabilities that may or may not be a problem for you. If you need a secure hash, it is probably best to avoid them anyway.

A hash rate is the measure of the computational power in a proof-of-work cryptocurrency miner, pool, or network. High hash rates equal better odds of winning.

Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature.

Researchers have found a new way to attack the SHA-1 hashing algorithm, still used to sign almost one in three SSL certificates that secure major websites, making it more urgent than ever to ...

The MD5 password hash algorithm is "no longer considered safe" by the original software developer, a day after the leak of more than 6.4 million hashed LinkedIn passwords.

Marriot revealed in a court case around a massive 2018 data breach that it had been using secure hash algorithm 1 and not the much more secure AES-1 encryption as it had earlier maintained.
